Xdebug, NetBeans, Dev Desktop and Win 7-can't get to work..

I can't for the life of me get anything to show up in the NetBeans Call Stack running easy Xdebug from Firefox. This is related to the video called "How hooks are invoked with module_invoke_all()"

Here's the relevant portion of my php.ini:
[Xdebug]
zend_extension = "C:\Program Files (x86)\acquia-drupal\php5_3\ext\php_xdebug-2.2.1-5.3-vc9.dll"
xdebug.remote_enable=1
xdebug.remote_host=localhost
xdebug.remote_port=9000
xdebug.remote_handler=dbgp
xdebug.idekey=netbeans-xdebug

Can anyone offer advice? Thanks in advance!
